RECORDING-LOGK CONTROL MEANS.

Application filed August 17, 1926. Serial No. 129,811.

My invention relates to looks, more particularly to recording locks inwhich a record is made when the lock-bolt is thrown, as for instance inrecording locks of the a type illustrated in Patent No. 1,112,.l19granted to me Sept. 29, 1914, and other patents of the same general typegranted to me, which are selected as an illustration of a type ofrecording lock to which the pres- Hi out invention may be appliedwithout however restricting the present invention to such particulartype of looks. The present invention has for its general object toprovide control-means that will prevent the lockbolt being thrown untilpermitted by such control-means, the control-means and the lock-boltactuating means being independently operated so that one may be underthe direction of one person and the other under 2- the direction ofanother person, so that the act of two persons is necessary foreffecting the unlocking of the lock-bolt and thus one will be a check onthe other and the unauthorized actuation of the lock-bolt is ef- Cfectively safeguarded.

The preferred embodiment of the present invention consists in thefeatures hereinafter particularly described and then sought to beclearly defined by the appended claims, reference being had to theaccompanying drawing forming a part hereof and in which Figure 1 is aside view of so much of a lock-bolt as is necessary to show the presentinvention applied;

Figure 2 is an end view of Figure 1, with the lock-bolt andcontrol-means in vertical section;

Figure 3 is a horizontal section on line 33 of Figure 1;

Figure 4 is a front view of a portion of the door to be locked and itsframeshowing in front elevation another form of the padlock hasp thatmay be employed;

Figure 5 is a section on line 5-5 of Figure 4. Y v

In the drawing the numeral 1 designates a casing secured to a door 2 andwhich may contain in its upper portion 3 a recording mechanism, andbelow, in the lock-casing i, a lock-blot 5 operated by a key applied at6 or by a key applied at 7 to turn the pinspindle S to throw thelock-bolt into its keeper 9 attached to the door-frame 10 or r toretract the bolt, which parts are of well known construction, forinstance such as typified in the patent hereinbefore mentioned, andfurther illustration not necessary for a full understanding of thepresent invention. While the recording lock of the character mentionedaffords practically absolute protection against unauthorized orfraudulent manipulation of the lock-bolt because of the record made bymanipulation of the lock yet for the purpose of affording additionalsecurity I provide a lock-bolt control which must be actuated before thelock-bolt is free for movement and this control-means requiring for itsoperation a key different from that for actuation of the lockbolt it isneces sary that both keys be employed before the lock-bolt can beactuated and the keys being in the possession or custody of differentpersons the concurrence of both custodians is necessary before the doorcan be unlocked and opened. The control-means under the presentinvention comprises a stop or locking dog thrown into the path of travelof the lock-bolt after the latter has been thrown into locking positionso that the lock-bolt cannot be retracted until the locking dog is movedout of its path of travel, said dog being held in its dogging positionby externally positioned means under the control of the custodian of thekey that locks said externally actuating means.

The preferred embodiment ofv this feature of the invention comprises aslidable pin or dog 11 positioned as illustrated in Figs. 1 and 2 to beprojected into the path of travel of the lock-bolt 5 after the latter isthrown into locking position in its keeper 9 so as to prevent retractionof the lockbolt until after the locking dog is moved out of itspath oftravel. The locking dog is projected through an opening in the bottomwall of the lock-bolt case by a suitable cam, as 12,attached to arotatable spindle 13 passing through the door 2, the cam preferablyacting. on the dog through the medium of a pivoted finger. 14 which hasa forked end 15 engaging the dog between shoulders 1'6 formed thereon sothat when the cam has been turned to the position shown in full linesFigs. 1 and 2 it has raised the finger 1a to the position shown in fulllines in the same figures and the dog projected to its locking position,and when turned to the position shown in the dotted lines in Fig. 1 thefinger has moved to its dotted line position shown in the same figure,by gravity, or under the influence of a spring 17, and the locking dogbrought to its dotted line indicated position, out of the path of thelock-bolt so that the bolt may be retracted. To the outer end of therotatable spindle 13 is attached one end of a hasp 18 which may be madein two parts with one connected to the other by a hinge 19 the free endof the hasp formed with a slot 20 to receive the hasp staple 21 adaptedto receive the hasp of any selected approved type of key padlock forsecuring the hasp in the position shown, which is horizontal, when thelock-bolt is in its locking position. hen the door lock-bolt is thrownto the locked position, in engagement with its keeper 9, the hasp, whichat other times stands or swings in a vertical position as shown bydotted lines in Fig. 2, is lifted to a horizontal, as shown in dottedlines in Fig. 1, and full lines in Fig. 3, which movement brings cam 12from its dotted line position shown in Fig. 1 to its position shown infull lines, same figure, thereby raising the pivoted finger 14 andlifting the locking dog 11 into position at the rear of lock-bolt 5 inits path of travel, in which position the dog is held by engagement ofthe free end of the hasp with the staple in which position it is lockedby a padlock, which may be the permutation type, whose pivoted hasp willengage the staple 21 in locking position, and thus the lock-bolt cannotbe retracted or thrown into unlocked position until the locking dog 11is moved out of its path by unlocking and removing the padlock whichlocks the hasp 18 to its staple 21. When the padlock is removed and thehinged part of hasp 18 swung from the staple 21, the hasp 18 will dropor swing to its vertical position so as to rotate spindle 13 and movecam 12 a quarter turn into the position indicated by dotted lines inFig. 1, whereupon the slidable dog 11 will drop so as to move out of thepath of movement of lock-bolt 5 and leave the latter tree to beretracted into unlocking position, the movement of dog 11 being bygravity, or positively effected by downward swing of finger 1 1 whichmay be aided by the spring 17. When the dog 11 is moved to unlockingposition and the 1ock-bolt retracted, the dog will lie below thelock-bolt and it cannot be moved to projected locking position until thelock-bolt has been thrown into locking position beyond the range ofprojection of the slidable dog. It follows from the foregoing that thelock-bolt control. that is the slid'able dog, cannot be actuated untilafter the lock-bolt has been thrown into locking position, and that whenthe dog has been thrown into locking or dogging position the lock-boltcannot be retracted until the lockbolt control, that is the dog, ismoved from its locking position, and thus the retraction of thelock-bolt is dependent upon withdrawal oi the locking dog and theprojection of the dog into locking position is dependent on thelock-bolt being thrown into locking position. Thus while the door islocked by a single lock-bolt its actuation is dependent on theconcurrence of two persons or two independent key custodians, one be ingthe custodian of the lock-bolt key and the other the custodian of thelock-bolt control, or padlock, key. This contributes to additionalsecurity, and safety against fraudulent or unauthorized locking andunlocking of the door. It also insures greater assurance that the doorhas been properly locked and placed under the protection of thelock-bolt control because so long as the hasp of the lock-bolt controlin vertical position it indicates that the slidable dog is not inlocking position and hence the lock bolt not guarded against retractionwhich is intended shall be the case so that itcan only be unlocked orretracted by first releasing the locking dog. Accordingly the custodianof the padlock key makes sure that the hasp 18 is brought intoengagement with the staple 21 and the padlock placed and locked whichgives assurance that the lockbolt has been thrown to locking positionand cannot be retracted without knowledge on the part of the custodianof the key of the lock-bolt control do". This construction avoids theuse of two lock-bolts to lock the door as in the present case only onebolt is used and is suilicient, and is safe guarded by the lock-boltcontrol under the control of an independent key.

The hasp 18 may be fixedly attached at one end to the rotatable spindle13, or it may be detachably secured thereto as illustrated in Figures4L- and 5. For instance, one end. oi the hasp may be formed with acurved lip 23 fitting in a correspondingly shaped socket 24 having anopen-side 25 and formed as a head to the spindle l3, and having sidecheeks 26 as illustrated in Figures 1 and 5 so that by placing the haspat the proper angle to the open mouth of the socket the curved lip 23will enter the socket and then turning the hasp so that it will extendfrom the socket in substantially the position shown in the drawing itcannot be withdrawn from the socket, and the cheeks 26 will prevent itfrom moving edgewise out of the socket. With the hasp coupled to thespindle as described when the hasp is placed in locking position it willremain securely attached to the spindle and cannot be removed therefrom.lVhen however the hasp is in its unlocked and pendent or hangingposition it can be detached from the spindle by turning it to the anglethat will permit its curved lip to be moved out of the socket. so thatwhen the lock-bolt is in its retracted position the hasp may be detachedfrom the spindle if desired, and when the door to be locked the hasp maybe replaced in its coupled relation to the spindle for the lockboltcontrol to function as previously described.

For the purpose of limiting the throw of the cam 12, stop pins 27 and 28may be positioned as illustrated in Figure 1 so that when the cam is inthe full line position shown in Figure 1 it will be stopped by the pin27, and when in the dotted line position shown in the same figure itwill strike and be stopped by the pin 28, and thus an overthrow of thecam in either direction will be prevented. a

It is preferred to place the cam 12, finger 1.4 and slidable dog 11within a case or shell 29 attached to the door below the lock-boltcasing 4 by bolts-30, or otherwise. The shell 29 is provided with aclosure'face-plate 81 formed with a lip 32 to fit over and interlockwith an upturned flange 33 formed on the shell and having at its upperedge a rearwardly extending plate or member 34 of any suitable widthdesigned to lie between l the top of shell 29 and bottom of lock-boltcasing 4 and at the rear formed with an upturned flange 35 which willfit in a recess 36 at the back of the lock-bolt casing as indicated inFigure 2 of the drawing. Under the construction described access cannotbe had to the interior of the shell to tamper with the lock-bolt controlmeans because when the shell 29 is attached to the door and thelock-bolt case then installed the face-plate of the shell 29 cannot beremoved without first removing the lock-bolt casing and thus fraudulenttampering with the parts is guarded against.

I have given a conventional illustration of a pad-lock 38 and pad-lockstaple 21 but any appropriate well known type of pad-lock and staplewith which it interlot=ks may be employed, nor is it necessary toillustrate details of the pad-lock as many different constructions areon the market, and the custodian under whose control is placed thelock-bolt control means may select the type of pad-lock and actuatingkey that best serves his purpose and with the view of preventingfraudulent manipulation of the parts so that the additional securitysought is obtained.

The invention is shown as applied to be used with a well known type ofrecording door lock but the recording means does not constitute thepresent invention and therefore need not be illustrated nor described indetail; and the invention in its broadest scope is capable of use with adoor lockbolt without recording means being associated with it.

IVhile I have illustrated and described with particularity the preferredconstruction and details of various parts it is to be understood thatchanges may be made therein and essential features of the invention beretained within the scope of the invention as sought to be defined bythe appended claims.
